Using a technique called "replay attack" a thief can use the key fob's transmitter to transmit a message which is recorded by the car's receiver. After the message has been recorded, a malicious device can transmit the transmission again to the vehicle receiver and gain access.

Based on the model and make, it may be possible to program new keys yourself or you may have to have an automotive locksmith assist you. Some car companies have an onboard programming procedure however, others require an advanced programming device connected to the OBD2 port.

The most commonly used method to program new keys for cars is to place the key fob into the ignition and engage it in a certain order. When the car is in "programming mode," one or more buttons on the fob are pressed to send the digital identification code to the computer. The computer then stores this code and removes the car out of programming mode.

Certain manufacturers require you to have a special advanced programmer to program key fobs. These are costly and difficult to use by the common person. It's best to leave the job to an automotive locksmith or dealer.
